COMBINATION 'WOODWORKING-MAOHINE.

Specification of Letters Patent. Patented Apr. 11, 1911.

Application filed January 22, 1910. Serial No. 539,586.

To all whom it may concern:

Be it known that I, 'LEWIS F. PARKS, a citizen of the United States, residing at Gin cinnati, in thecounty of Hamilton and State of Ohio, have invented certain new and useful Improvements in Combination Woodworking-Machines, of which the following is a specification.

It is the object of my invention to provide a combination wood-working machine comprising various cutting instrumentalities so combined and arranged that the same may be used conjointly or in close relation without interference with each other and be so mounted as to economize in space and cost of construction, and the invention will be readily understood from the following de scription and claims, and from the drawings, in which latter:

Figure 1 is a right side elevation of my improved device. Fig. 2 is a front elevation of the same. Fig. 3 is a plan View of the same partly broken away, and with the upper saw-wheel frame omitted for better illustration of parts. Fig. 4 is a rear elevationof the same, partly broken away. Fig. 5 is a longitudinal section taken on the axial plane of the main mandrel, on the line zz of Fig. 1, showing said mandrel and its attendant parts. Fig. 6 is a cross-section on the line y-y of Fig. 3, the rear end of the frame and the parts mounted thereon being broken away. Fig. 7 is a cross-section on the line zvm of Fig. 3. Fig. 8 is a perspective detail of the corner connection of the main frame. Fig. 9 is a perspective view of the guard-block for the circular saw-blade. Fig. 10 is a side elevation of the auxiliarytable. Fig. 11 is a perspective view, partly in vertical section, of the vertical stock-support for the same, showing a piece of stock guided thereby into range of the lower side of the auxiliary cutter-head; and, Fig. 12 is a horizontal section of the band saw-guide, taken on the line w-w of Fig. 1.

I do not herein broadly claim the arrangement of the plurality of tables in front of the cutter-head and common rear table, and the side-gage therefor, showing, describing and claiming said features in a separate application therefor filed by me I August 5, 1910, Serial No. 57 5,740; nor do 1 represents the main frame which is 7 shown constructed of angle-irons bolted together and which has a reinforcing base composed of side beams, preferably of Wood. Thus the main frame comprises front angleiron uprights 2, rear angle-iron uprights 3, and intermediate angle-iron uprights 4, which are connected at their bottoms at the respective ends of the machine by basebeams 5 set up on edge. Intermediate angleiron cross-girts 6 are bolted to all of said uprights at the respective ends of the machine by bolts 7. Upper angle-iron crossgirts 8 are bolted to the front uprights and intermediate uprights at the respective ends of the main frame, and arranged for forming a gap 10 between the intermediate uprights and rear uprights above the intermediate cross-girts. The front and intermediate uprights located in front of said gap are respectively connected at the respective ends of the main frame by an upper angle-iron longitudinal girt 11 and the rear uprights are connected by an upper angle-iron longitudinal girt 12 and an intermediate angle-iron longitudinal girt 13. The manner of connecting the uprights and upper longitudinal and cross-girts where they meet to form corners is preferably as follows (see Fig. 8): One of the wings of the upper cross-girt and one of the wings of the upright are bolted together by a bolt 14, one of the wings ofthe longitudinal girt and the other of the wings of the upright are bolted together by a bolt 15, and the other of the wings of the longitudinal girt and the other of the wings of the cross-girt are bolted together by a bolt 16, the flat faces of said wings which are bolted together being presented toward each other. The uprights and base-beams (see Figs. 1 and 2) are connected by angle-iron longitudinal girts 17, bolted to said uprights and base-beams respectively by bolt-s 18 19, thereby bracing the frame.

25 is a main table, the frame work of which is constructed of end angle-irons 26 (see Figs. 5, 6 and 7), connected by longi tudinal angle-irons 27 secured thereto by bolts 28. The table has inverted channelirons 29 extending at right angles to the main mandrel and secured to the framework. The end angle-irons of the table eX- tend beyond the rear of the rear longitudinal angle-irons, where they are pivoted to the main frame adjacent to the intermediate uprights on pins 31, located on angle-iron clips 32 secured to the main frame. The table is provided at its forward end with depending bars 33 having slots 34 (see Fig. 2) through which clamp-bolts 35 are received into the main frame, by means of which the table is clamped in adjusted positions at various elevations. I

36 is a main mandrel journaled in bearings 37 on the main frame. (See Figs. 3, 5, 6 and 7 This mandrel as shown has a main cutter-head 38, a circular saw-blade 39, and a supplemental cutter-head 40 secured thereto, one of the bearings 37 for the main mandrel being located between said main cutter-head and circular saw-blade, the in.- verted channel-irons 29 being located above said bearing between .said main cutter-head and circular saw-blade. The main mandrel also has thereon an auxiliary cutter-head 41 located adjacent its end, (see also Figs. 2, 10 and 11) adjoining which there is a rubbing-collar 42, the auxiliary cutter-head and rubbing-collar being clampedin place by a clamp-nut 43. The end of the main mandrel is also shown provided with a bore 44 in which the shank of an auger-bit 45 is re ceived, the latter being clamped in place by a set-screw 46 threaded into a collar 47 and through an opening in the wall of the bore against the shank of said auger-bit. The main mandrel is provided with a pulley 48 for operating the same. The bearings 37 are secured to the upper cross-girts 8 be tween the front uprights 2 and the intermediate uprights 4.

An adjustable table-plate 51 is located (see Figs. 1, 3 and 6) at the rear of the main cutter-head, and a plurality of table-plates 52 53 (see also Fig. 2) are located at the front of said main cutter-head, either or both of said plurality of front table-plates acting in conjunction with said single rear table-plate. By this means a roughing and a finishing cut may be imparted without intermediate adjustment of tables, or greater depth of cut may be obtained at one side of stock which is for instance of irregular shape in cross-section, and other operations performed without readjustment of parts.

. These table-plates are each provided with inclined guides 54, formed Within the bodies of said plates by under-cutting, forming a cheap construction, arranged to rest on setscrews 55 adjustable in threaded apertures 56 in the horizontal angles of the longitudinal angle-irons of the frame-work of u the table, clamp-nuts 57 holding the setscrews in adjusted positions. table-plates has a depending lug 58 in which a hand-screw 59 is journaled against endwise movement, said hand-screws being adjusted in threaded apertures 60 in the vertical wings of the front and rear angle-irons of the framework of the table. The setscrews 55 adjust the table-plates to the desired level and the hand-screws 59 adjust the same to elevation and toward and from the main cutter-head 38. Each of the, tableplates is clamped in adjusted positions by a clamp-screw 61 received in a threaded aperture 62 in the table-plates and surrounded by a tube 63 having end abutment against a hand-wheel 64 of the clamp-screw and a cross-bar '65 received shiftably against the lower face of the rigid frame-work of the table.

Adjustable table-plates 71 72 are received respectively at the front and rear of the supplemental cutter-head 40. Each of these latter table-plates is adjusted to level position by means of set-screws 73 received in threaded apertures 74 in the horizontal wings of the longitudinal angle-irons of the framework of the table and held in place by nuts 7 5. For elevating therear table-plate I 'provide shims 76 of right angular form in cross-section, the horizontal wings of which are arranged .to be received between the upper ends of the set-screws 73 and the lower face of the table-plate, and the vertical wings of which are arranged to be placed against the vertical wings of the angle-bars of the framework of the table for positioning said shims. Each of these table-plates is arranged to be clamped in adjusted position by a clampscrew 77 Each of the threaded into a threaded aperture 78 of the table-plate and encompassed by a tube 79' having end abutment against a hand-Wheel 80 and a cross-bar 81 clamped against the lower face of the rigid framework of the machine.

86 is a side-gage at one side of the circular saw-blade 39 and 87 is a side-gage at the other side of said saw-blade, the side-gage 86 operating adjacent the main cutter-head 38 and the side gage 87 operating adjacent the supplemental cutter-head 40. (See Figs. 1, 2, 3 and 5). The side-gage 86 comprises a gage-plate 88 which is articulated at 89 90 to links 91 92, the link 91 being pivoted at 93 to a slide 94 and the link 92 being adj usted with relation to said slide by having a slot 95 through which a clamp-screw 96 passes into threaded connection with said slide.

By these means angular adjustment l is given the gage-plate. The slide is mounted on brackets 97 secured to the framework of the table and has a bar 98 received in a clamp 99, the clamp being adjustable lengthwise of the brackets in slots 100 therein. These means provide lateral adjustment for the side-gage 86. The side-gage 87 (see Figs. 2, 3, 5 and 6) comprises a gage-plate 105 rigidly secured to an angle-iron 106.

107 is an inverted channel-iron, which forms a slide for the angle-iron, which is spaced from the gage-plate by a block 108 for raising the latter so as to ride freely on the table-top at either side of the circular saw-blade.

109 is a brace rigidly secured to the angleiron 106 and to the rear end of the block 108, the angle-iron 106 being also secured to said block.

The inverted channel-iron 1.07 rides on clamp-collars 114, the outer flange of the channel-iron riding upon the reduced ends 115 of said collars and said collars being provided with flanges 116 which are re ceived in the under recess of said channeliron and is clamped by clamping the rear depending flange of said inverted channeliron between said flanges of the collars and the framework of the machine by means of clamp-screws 117 threaded into the framework of the table.

120 is a guard-bar (see also Fig. 9) for the circular saw-blade and has an arc-recess 121 in its lower face in which the upper portion of the periphery of the circular sawblade is arranged to be received. This guard-bar is releasably attachable to either side-gage 86 or 87, the side-gage 86 being provided with apertures 122 and the sidegage 87 being provided with apertures 123 through which clamp-screws 124: are arranged to be selectively received and to be threaded into threaded apertures 125 in both sides of the guard-bar.

For limiting the downward movement of the main table, (see Figs. 6 and 7), setscrews 126 are threa ded into the main frame and held in place by jam-nuts 127, the main table being arranged to rest upon the setscrews when in normal or level position.

Operating in conjunction with the auxiliary cutter-head 41 at the end of the main mandrel, (see Figs. 2, 3, 5 and 10), there is a vertical stock-support 131 which surrounds said mandrel and is adjustably secured to the main frame, and enables stock of various forms to be guided in vertical positions about the auxiliary cutter-head from all radial directions. Thus in Fig. 11 I have shown the same as applied in providing a curved strip 130 with a rabbet, the curved strip being passed about under the auxiliary cutter-head against the stock-engaging surface of said stoclcsupport. The vertical stock-support is arranged to be adjusted axially of the main mandrel by having slotted bars 132 secured thereto, clamp-screws 133 being received through the slots in said bars and threaded into the main frame for exposing more or less of the length of said cutter-head to the stock being operated on. \Vhen operating on stock from the upper part of said auxiliary cutter-head, I provide an auxiliary table 1341 which is provided with a recess 135 in its upper face, in which the cutter-head rotates, the auxiliary table bein a one-piece structure for insuring that the stoelcsurfaces shall be level with each other irres wctive of any adjustment for elevaticn which may be given either end of said table. The adjustment for elevation permitted and the auxiliary table clamped in adjusted positions by clamp-screws 136 received through slots 137 in said table and threaded into said vertical stock-support. If desired, the table slu'faces of said auxiliary table may be on plates 138 139 adjustable toward and from the auxiliary cutterhead and held in adjusted positions by clamp-screws 1&0 1411 received through slots 1-12 143 in said auxiliary table and threaded into said plates. 1

146 is a boring table slidable axially with relation to the main mandrel toward and from the boring-bit 4:5 in the end of the latter. (See Figs. 1, 2, 3, 1 and 5). It is mounted on slotted uprights 1417 adjustable on an angle-bar 148, to which it is clamped by bolts 149. One end of the angle-bar 148 has an inverted channel-bar 150 bolted thereto, the latter being slidable on the horizontal wing of an angle-bar 151 secured to the main frame by bolts 152 about which collars 153 are received for spacing said angle-bar from the uprights of the main frame for accommodating the rear flange of said inverted channel-bar. A clip 154- secured to said inverted channel-bar and received under the horizontal wing of said angle-bar holds the parts in sliding relation. The other end of said angle-bar 1 18 is slidable loosely on an angle-iron 145 secured to the main frame, forming an economical construction which is accurate and in which all danger of binding is avoided. This manner of construction avoids all finishing of the sliding faces.

155 is a boring mandrel journaled in bearings 156 releasably secured by bolts 157 to the intermediate cross-girts 6 between the front uprights 2 and intermediate uprights 4. (See Figs. 1, 2, 3 and 1.) At one of its ends said boring-mandrel is provided with a socket-block 158 for a boring-bit 159, the socket-block having spline-connection 160 with said mandrel and arranged to be shifted lengthwise of said mandrel by a lever 161 articulated with the main frame through a link 162 and having a stop-rod 163 thereon provided with a stop 16 1 for limiting releasably secured to the intermediate crossgirts 6 between the intermediate uprights 4 and rear uprights 3 in the lower portion of the gap 10 between said intermediate and rear uprights. The said mandrel supports a lower band saw-wheel 183. 184 is an upper band saw-wheel, a band saw-blade 185 being received about said band-saw wheels.

186 is an upright supported on the rear upper longitudinal girt 12 of the main frame and releasably secured thereto by bolts 187. Tubes 188 189 project forwardly from said upright, an upper band-saw guide 190 being secured to the upper tube 188. The

forward end of the lower tube 189 supports the table 193 and is in turn supported from the intermediate longitudinal girt 11 of the frame by the recessed yoke 194, the recess 195 whereof opens forwardly and provides clearance between the table 193 and the main table 25, the table 193 being located above the horizontal plane of the main table and at the rear thereof. The recessed yoke is releasably secured to the main frame by a belt 196. The construction permits attachment or removal of the band sawing device.

The upper band saw-guide 190 (see Fig. 12) comprises a casing 197 in which there is a pocket 198 which receives disks 199 200 wholly therein and having ball bearings 201 therebetween and centered and held in place by a screw 202. The disk rotates about said bolt. The casing has lugs 203 and 204 to which side-blocks 205 206 for the band saw-blade are secured, the blocks being received against the outer edge of the wall 207 of said pocket which extends forwardly of the outer face of the outer one of said ;,disks for distancing said blocks from said devices. pulleys 212 for operating the same.

213 is a supplemental overhanging frame (see Figs. 1, 2 and 4) constructed of angleirons bolted together and in turn bolted by bolts 214 to the rear upper and intermediate longitudinal girts 12 13 for forming a construct-ion in which said supplemental frame may be releasably attached to said main frame. This supplemental frame forms a support for an upright shaping or friezing device, of which 215 is the upright cuttercarrying shaft arranged to have a cutter 216 secured thereto. This upright shaft is journaled in bearings 217 secured to the supplemental frame. It is in vertical plane coincident with the vertical plane of the driveshaft and has a friction bevel-wheel 21.8 at its lowerend.

219 220 are connected friction bevel-wheels which as shown have spline-connection 221 with the drive-shaft, the hub 222 of said connected friction-wheels having an annular groove 223 in which pins 224 of a yoke-lever 225 are received, the yoke-lever being pivoted at 226 to a bracket 227 of the supplemental frame and operated by connected It is provided with tight and loose treadles 228 229 pivoted at 230 to the floor and having articulated connection with the yoke-lever by-a link 231.

232 is a table which is adjustable up and down by means of a screw-rod 233 j ournaled against endwise movement in a bracket 234 on the supple-mental frame and having threaded connection with a lug 235 on a slide 236 secured to said table, the slide slidable on a guideway 237 of the supplemental frame and held in adjusted position by a clamp 238. The table 232 is located to rear of the main table 25 and is substantially at the same normal elevation therewith.

The drive-shaft is provided with a pulley 241 which is loose on said drive-shaft but is arranged to be connected therewith for rotating with the same by a clutch 242, shifted in and out by a lever 243. When connected with said drive-shaft the pulley 241 is arranged to operate the main mandrel 36 by means of a suitable belt 239 passing there over and over the pulley 48 on said main mandrel. 245 is a pulley also loose on said drive-shaft but arranged to be connected therewith by a clutch 246 operated by a lever 247 and when so connected is arranged to operate the lower band-saw wheel mandrel by means of a belt 240 passing thereover and over a pulley 248 secured to said mandrel.

249 is a pulley secured to the drive-shaft and is arranged to operate the boring mandrel by means of a suitable belt 244 passing about said pulley 249 and a pulley 250 secured to said boring mandrel.

By referring to Fig. 1 it will be seen that the various shafts are so arranged that operation of the same may be had without interferenee with each other. The relative location between the main mandrel, the auger mandrel and the lower band-saw wheel-mandrel and drive-shaft is such as to allow the longest belt to be passed over the pulleys on the drive-shaft and the main mandrel, this main mandrel requiring the greatest relative power to be applied thereto. It is located so that a right line drawn between its rotary axis and the rotary axis of the drive-shaft will be between a right line drawn between the rotary axes of the auger mandrel and drive-shaft and a right line drawn between the lower band-saw wheel-mandrel and said drive-shaft, thus permitting said various mandrels to be operated within compact space and without interference, by straight belts which pass directly between the driveshaft and said respective mandrels.

My improved device forms a construction in which the various wood-working agencies and their attendant parts may be selectively embraced or added as desired, and so arranged that the same may be conjointly or selectively employed without interference with each other and so arranged as to be operated by a common drive-shaft. It further forms a cheap construction which is readily assembled and by means of which a great variety of operations may be performed.
